Parameters
number: Specifies the maximum number of ping packets, in the range of 0 to 10. A value of 0 indicates
that the DHCP server does not perform address conflict detection.
Usage guidelines
To avoid IP address conflicts, the DHCP server pings an IP address before assigning it to a DHCP client.
If a ping attempt succeeds, the server considers that the IP address is in use and picks a new IP address.
If all the ping attempts are failed, the server assigns the IP address to the requesting DHCP client.
Examples
# Specify the maximum number of ping packets as 10.
